Considered
Westwood's seminal work, An Introduction to the Modern Classification
of Insects illustrates the sophistication of the hobbyist of the
period. Intended for the amateur entomologist, An Introduction consisted
of more than 1,000 pages and sought to bridge the gap between general
overviews of insect life and the very specialized catalogs of insect
genera and species. The work focused on the classification of insects
into orders and families.

An
Introduction to the Modern Classification of Insects earned Westwood
the Royal Medal of the Royal Society in 1855. The copy owned by NCSU's
Special Collection's Department is autographed by Westwood for Dutch
entomologist, Willem DeHaan (1801-1855).
